# Hybrid Inverter vs PCS: Which for Small/Medium C&I? A hybrid inverter integrates PCS+EMS+STS+ATS for fast deployment; a PCS suits modular system integration. A comparison selection guide. Both do battery↔AC; the difference is integration A hybrid inverter integrates PCS, EMS, STS and ATS out of the box; a PCS is modular and freely combinable. Hybrid inverter line-up [SP60/50/40/30HCG2](/en/product/sp60-50-40-30hcg2): 30–60kVA, wide DC voltage + high current, built-in STS, diesel-hybrid, paralleling. [SP30/25/15HBPS](/en/product/sp30-25-15hbps): 15–30kVA small, built-in STS, for farm/villa/small island. [Leona-H135K](/en/product/sp135hapss): 135kVA wall-mounted split, grid-forming, 20+ off-grid parallel, IP65. How to choose **Hybrid inverter**: small/mid C&I, farm/villa, microgrid, fast delivery, high protection. **PCS/module**: large microgrid, fine cluster management, OEM/skid integration (e.g. [SP125HCPS](/en/product/sp125hcps)). Shared plug-in advantage: PCBA sealed / airflow isolated, ≥10-year design life. ## Big price gap between hybrid and PCS? Hybrid ships faster via integration; modular PCS wins on unit cost and flexibility at large scale — compare by project size. ## Which for small island/villa? 15–60kVA hybrids (SP30/25/15HBPS, SP60/50/40/30HCG2) with built-in STS suit small off-grid backup. ## Can hybrids parallel? Yes. SP60 series and Leona-H135K support diesel-hybrid and paralleling; Leona-H135K 20+ off-grid. ## Which for grid-forming? Grid-forming hybrid: Leona-H135K; grid-forming module: SP125HCPS.
